DESCRIPTION

The MP1522 is a step up converter that generates up to a 25V output voltage from a 2.7V to 25V input. It uses a current limited Variable Frequency control algorithm to optimize efficiency and minimize external component size and cost. The internal 0.5Ω N-Channel MOSFET switch can withstand up to 28V allowing the MP1522 to produce high output voltage with high efficiency.
